SQL Developer Will Remote Connect / SQLplus Will Not
Jul 19, 2010
When I try to remotely connect to an Oracle schema using SQLplus, I consistantly get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Yet I can connect to the same machine, from my own machine just fine using SQLDeveloper.Here are the details I have collected so far
- I am using the instantclient for OS X
- export DYLD_LIBRARY_PATH=/Users/jeff/instantclient
- export ORACLE_HOME=/Users/jeff/instantclient
- export TNS_ADMIN=/Users/jeff/instantclient/tns
The command line i ran : ./sqlplus seam_classoft/seam_classoft@//oracle11gtest.terida.net:1521/orcl
Its behind a VPN, so I'm not worried about posting my info.
My /Users/jeff/instantclient/tns/tnsnames.ora that I copied directly from the server looks like this:
I've tried changing SERVICE_NAME to SID = orcl, no change inbehavior. My original guess was that the database wasn't registered with the listener, but that would mean sqlDeveloper should fail as well, but it works.Here is out put of lsnctrl status:

I am able to connect to DATABASE from SQLAssistant only when I provide string like ABOVE........If I dont mention the SERVICE, m unable to connect to DB.Now the biggest issue is with SQL Developer.....m not at all able to connect to DB using SQL Developer.
I installed oracle 10g and developed simple software using forms 6i. Its working well as a stand alone system.
I want to share it in network. so I installed forms 6i as oracle client , copied the tnsnames.ora from the oracle installation path to forms installation path.(inside NET80/Admin folder)
When i try to connect with user name and password , it comes ORA-12203 Unable to connect to destination. I checked LSNRCTL in the database machine, it is listening.
I am using Report Builder 10.1.2.0.2. There is a table in a remote database with synonyms/links defined. I am getting error trying to access those tables. DBA says links/synonyms are correct and I am also able to access that table from SQLTool without error.
I can do a select statement on those tables from 'SQL Query statement' in data model.
Error is generated only if I try to use those tables in 'Formula' or in function/procedure.
I have a database up and running (including listener) on machine A. From that machine, everything seems fine. However, when I try to connect to it from another machine (say, machine B) on the network, the connection cannot be established (exact message: connection to database failed: The Network adapter cannot establish the connection).
I can successfully ping machine A from machine B. The machine A db is a default install (ORCL).
Is it possible the DB listener is not configured properly to connect to remote clients? On machine B, I have oracle tools such as SQLPLUS, Oracle Net Manager, and Net Configuration Assistant.
I am trying to connect to a database located at my work from at home. I am running into the following issue (see command and error below):
ansichart@ansivm:~/src/perl$ sqlplus aspxdba/********@aspxp2 SQL*Plus: Release 11.2.0.3.0 Production on Thu Jul 18 21:15:09 2013 Copyright (c) 1982, 2011, Oracle.

I have verified that I can establish a TCP connection to this DB server on the port specified, using the same info from the TNSnames.ora file (see below):-

I have another terminal opened up to a server at work and I can connect to the DB with sqlplus just fine. I verified that the record for this database on the tnsnames.ora file is the same as it is at work. In conclusion, I can connect to the Database at work, but I cannot at home, even though I am using the same connection information and verified that port 1521 is accessible on this Database server from at home. So why can't I establish a DB connection?
After restarting the listener, we could connect using the connect identifier from the local server. However, when trying to connect from a remote client we received the error of "no listener". In the remote client the identifier is defined with host=ip_address. TNSping from the client to the host was successful.
When we changed listener.ora to host=up_address we could connect ONLY from the remote computer. Only after changing the host in tnsnames.ora file to the IP as well - we could connect from both the local server and the remote client.
I usually use host=localhost in the listener file (and the local tnsnames file) and never had this problem before.
I have a strange problem of connecting Oracle Forms6i from our Remote site.actually we change our IP address of lease line, we connect to it.but when we connect locally,forms are running without any problem,but when we connect globally or from other sites it can't able to connect,even sql prompt and toad also connect from remote site,but when we try to connect forms(forms runtime) it gives error message(ORA-12203: TNS:unable to connect to destination).when we connect this application from local application(Forms) it can connect well but from globally it can't able to connect.
I have created a function for knowing the status of link which connect me with remote database.function is as follows
--------------------------------------------------------------------------------------------- CREATE OR REPLACE FUNCTION get_status_db_link (p_db_link_in VARCHAR2) RETURN NUMBER AS rows NUMBER; v_code NUMBER; v_errm VARCHAR2(64); [code]....
Now functin should returns 1 when link is up and it should return 0 when link down but sometime when link is down it continues showing executing it hang my pc.
it seems to me that the file tnsnames.ora is not read when i execute sqlplus.whit the command: sqlplus username / password @ servicename i receive the error ORA-12154, while if i pass the whole connection string i can connect without problems
when i try to connect with sqlplus or toad then i get an error
Microsoft Windows [Version 6.1.7600] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:Users>sqlplus SP2-1503: Unable to initialize Oracle call interface SP2-0152: ORACLE may not be functioning properly C:Users>
and i want to tell what i do before it-my all files were be converted in .FLT then i shorted out this problem after that when i tried to connect with sqlplus or toad then i get above error.and i have restarted my system but throwing same error.
I have registered an APEX (Oracle) online database and I can connect to database online.But my problem is how to define a connection string that can connect from the program written in C# to connect to APEX account(apex.oracle.com).I even don't know how to use the tool Oracle SQL Developer to connect to APEX account.
I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter: Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is: CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
Acer laptop, Intel Processor w/ Windows 7 Professional (64-bit) Delphi 2010 Professional Oracle XE (+ the Oracle XE client that comes with it)
I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator. - Data source name: bt_user - TNS Server Name: localhost/xe - user bt_user - Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC) - Set database name to "bt_user". - Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form. - Select "connection string" and open the dialog. - Click "build string". - Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection. - In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1) - Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?
I want to update my table base on changes in a column of a table from remote database automatically. I just want to pick some updated column then update to my own. i have made a trigger but failed.

We have eight servers. One of them is for centeral management. The other seven is for development and test databases. Every night, we start a process which exports database schemas (without data) into the centeral server. An example of the process we run is just like below:
As you can see, we use @dev to connect remote database. But dump file is created in local (centeral) server. We are planning to use datapump instead of classic export in future. But I couldn't find a solution, that could take a database export in a remote server and create dump file in local. I have looked at NETWORK_LINK parameter; but it doesn't seem to work for our case.
Is it possible to backup a remote database with datapump and make it create dumpfile in local? (Of course we can use some solutions such as NFS, but we really not prefer this; if datapump has ability to remotly backup.)
We have access to a remote Oracle database in Germany and need to insert selected data to our local Oracle database. Our problem is that we have to do several joins (7 tables) on the remote database as well as using one where clause (always the same: P.T_LIEF_LFNT_1='12803193').
Unfortunately we do not have rights to create a view on the remote database. Is there another way to send the entire query to the remote database for processing? Also, the query returns approximately 34,000 rows.
Here is our current query:
INSERT INTO PRIMUS(PARTNO, SORT_FORMAT, TP_WORKSPACE,
I working on data transferring from one database server to another database server. but at starting i want to check weather remote database is connected or not?
for e.g.
a := get_remote_connection; --- Calling function for check remote connection return boolean if a then <call my data_transfer_proc> else exit; end if; reply.
I have created a remote link to a sql server db in oracle 11.0.7 works fine in sql plus. I can select tables by select * from table@linkname...the link is a public link But when I put it in the procedure it says invalid table name. then I created a public synonym for the table - i can select from the synonym in sql plus - but in the procedure it says synonym translation invalid...Also I cant grant any privileges to the synonym as it says ddl operations are not allowed on remote objects
I have 2 database . One is production and other is Integration and I have one table "emp" which is on integration server and a synonym of that table with the same name"emp" on production. On production we have a proc in which we are using "emp", but some time our integration server goes down, so is there any way to ping the integration server inside the proc and if it returns success then we will execute the rest of code of proc , otherwise it will send a mail to us saying that integration server is down.
We are running Oracle 11.2.x DB on Solaris platform. Looking for a way to see if I can send alert log and listener log to a remote syslog server? I know there are some other methods like Epilog and some other scripts that could be used, but wondering if there is a "built-in" method to accomplish this?
